hello-do

This repo deploys a simple web service as a Digital Ocean App.

Terraform

The required resources are created by the terraform code under terraform/.

Once "gotcha" here is that we want to create both the DOCR (Digital Ocean Container Registry) to host our image, as well as the DO App that runs the image. Creating the App requires an image to be present in the container registry, so the resources must be created in two separate applies.

Note the outputs.

• docr_repo is where we will push our images
• app_live_url is our app's endpoint

Dagger

The Dagger pipeline in ci/main.go builds our image and pushes it to DOCR.

1. Authenticate docker to DOCR: docker login registry.digitalocean.com
2. Run the Dagger pipeline: go run ci/main.go
3. Once the pipeline is complete, the DO App will detect a new image at :latest and automatically deploy the new version of our image
4. Send a request to the app_live_url from above: curl $app_live_url. You should get a successful response Hello
